Add additional attributes to client

[dmohanty-r7]

As brought to attention by @chrisdlf : Currently we are only capturing the peer_native_os attribute from the SMB_COM_SESSION_SETUP_ANDX response in the client.

https://github.com/rapid7/ruby_smb/blob/master/lib/ruby_smb/client/authentication.rb#L37 https://github.com/rapid7/ruby_smb/blob/master/lib/ruby_smb/client/authentication.rb#L79

In REX we additionally get the following attributes from SMB_COM_SESSION_SETUP_ANDX

• peer_native_lm

also in REX we get these from the NTLM type 2 challenge blob:

• default_name
• dns_host_name
• default_domain
• dns_domain_name (this one has been removed recently from Rex but it was there before)

https://github.com/rapid7/metasploit-framework/blob/master/lib/rex/proto/smb/client.rb#L561

We should be adding these additional useful attributes of information in the client.
